Summary

Create comprehensive specification for BpkCheckboxCard component - a composable checkbox card with flexible content composition, multiple visual variants, and full state management.

Key Features Specified

  • Composable subcomponents (Root, Control, Content, Label, Description, Indicator, HiddenInput, Addon)
  • 3 visual variants: default, contrast, surface-contrast
  • 2 radius options: square and rounded (8px)
  • Indicator placement control: start or end
  • Full checkbox state support: checked, unchecked, disabled, invalid (ARIA-only), readonly
  • maxW/maxH props for sizing constraints
  • BpkText-based Label/Description with context-aware styling
    • Default: bpk-heading-5 (label), bpk-footnote (description)
    • On checked: text-on-dark-day for contrast on colored backgrounds

Clarifications Resolved (6 total)

  1. Invalid state: ARIA-only (no visual styling)
  2. Sizing: maxW/maxH props for max constraints
  3. Focus styling: Uses Backpack focus ring utility
  4. Label defaults: bpk-heading-5 + text-primary-day
  5. Description defaults: bpk-footnote + text-secondary-day
  6. Checked state text color: text-on-dark-day for accessibility

Testing & Success Criteria

  • 13 functional requirements fully specified
  • WCAG 2.1 Level AA accessibility compliance
  • RTL language support
  • 12+ success criteria for measurable validation
  • Keyboard navigation and screen reader support

Files

  • specs/002-checkbox-card/spec.md: Complete specification
  • specs/002-checkbox-card/checklists/requirements.md: Quality checklist

Remember to include the following changes:

  • Ensure the PR title includes the name of the component you are changing so it's clear in the release notes for consumers of the changes in the version e.g [Clover-123][BpkButton] Updating the colour
  • README.md (If you have created a new component)
  • Component README.md
  • Tests
  • Accessibility tests
    • The following checks were performed:
      • Ability to navigate using a keyboard only
      • Zoom functionality (Deque University explanation):
        • The page SHOULD be functional AND readable when only the text is magnified to 200% of its initial size
        • Pages must reflow as zoom increases up to 400% so that content continues to be presented in only one column i.e. Content MUST NOT require scrolling in two directions (both vertically and horizontally)
      • Ability to navigate using a screen reader only
  • Storybook examples created/updated
  • For breaking changes or deprecating components/properties, migration guides added to the description of the PR. If the guide has large changes, consider creating a new Markdown page inside the component's docs folder and link it here

[002-checkbox-card] Add Ark UI dependency clarification
04dd0ce 
## Summary

Clarify that @ark-ui/react will be added as a shared peer dependency
in the root package.json for centralized version management across
the Backpack monorepo.

## Decision

- Dependency: @ark-ui/react (unstyled checkbox primitive)
- Location: Root package.json (peer dependency)
- Rationale: Centralized version management; shared across components;
  easier updates and reduced duplication

## Files Updated

- specs/002-checkbox-card/spec.md: Added Q7 clarification

[BD-002][BpkCheckboxCard] Enhance specifications with implementation …
20df876 
…guidance

Add comprehensive implementation guidance across all specification artifacts:

**spec.md improvements**:
- Design token validation table with 12 tokens, Scss usage patterns, and availability status
- Corrected token import syntax: tokens.$bpk-token-name from @use '../../bpk-mixins/tokens'

**plan.md improvements**:
- Type definitions: Complete BpkCheckboxCardProps, BpkCheckboxCardContextValue interfaces, and all subcomponent props
- Ark UI integration pattern: ASCII diagram, responsibility separation, no-conflicts guarantee
- Dynamic color behavior rules: Label/Description/custom content/Addon color handling per state
- Themeable properties: 5 tokens mapped to CSS variables with implementation examples
- Performance constraints: Bundle size, render performance, and accessibility overhead targets

**tasks.md improvements**:
- T022b: New task for implementing themeable properties with proper @use statements
- T015: Detailed Storybook story requirements for basic label rendering
- T022: Enhanced with four story scenarios (Description, Addon, Full, asChild)
- T031: Explicit variant story matrix (default/contrast/surface-contrast)
- T050: Detailed state stories (Disabled, Readonly, Invalid, Sizing)
- T051-T055: Expanded accessibility test coverage with 23 specific test scenarios

Readiness score: 9.5/10 → 9.8/10 (implementation-ready specifications)
